You'd have to use a diode. Trust me, it is very unlikely that the cap would be
able to deliver much in the way of power to drive the train (they only hold a
few joules of energy, not much when compared even with the speed of a Lego
train).
I think constant lighting is out for the same reasons, just not enough energy
density in the cap.

| oups! don't try it or be very carefull. the capacitor is a 1Farad 3Volts max capacitor. that would limit the voltage that you can put your regulator at 3V. If you go past that voltage, you'll end up blowing up your capacitor (quite a messy situation (...) (23 years ago, 7-Feb-01, to lugnet.trains)
